New Post: Insert silence at start and add silence to end

    private void InsertSilence(WaveFileWriter writer, Double milliseconds)
    {

        Double avgBytesPerMillisecond = (Double)writer.WaveFormat.AverageBytesPerSecond / 1000F;

        Int32 silenceSize = (Int32)(milliseconds * avgBytesPerMillisecond);
        silenceSize = silenceSize - silenceSize % fileIn.WaveFormat.BlockAlign;

        Byte[] silenceArray = new Byte[silenceSize];
        writer.Write(silenceArray, 0, silenceArray.Length);

    }
